More than 45 million acres of trees were cut down last year — an area twice the size of Portugal — according to an analysis
by the University of Maryland and Google. Tropical nations lost more than half of that total — nearly 25 million acres of tree cover, an area roughly the size of South Korea. Brazil and Indonesia, the two countries most often associated with deforestation, had been making gains toward stemming the problem, but 2014 saw an uptick in tree cover loss in both countries. The situation is especially concerning in Cambodia, where deforestation is accelerating faster than anywhere else in the world due to the development of rubber plantations. Last year Cambodia lost three times more tree cover than in 2001, the analysis found.
